Description

Technical Field

[0001] The utility model belongs to the field of drilling electrical equipment, and in particular relates to a safety protection mechanism for drilling electrical equipment. Background Art

[0002] Drilling is the work of drilling holes in the ground using mechanical equipment or manpower. It usually refers to the project of drilling wells and large-diameter water supply wells for the exploration or development of liquid and gaseous minerals such as oil and natural gas. Drilling is widely used in economic construction.

[0003] The patent application with publication number CN215301328U discloses a safety protection mechanism for drilling electrical equipment, including: a main component and a protection component, wherein the main component includes an electrical cabinet, a storage plate, an annular shell, a ventilation pipe and a thermal insulation coating; the protection component includes a PLC controller, a combustible gas detector, a toxic gas detector, a temperature sensor, an audible and visual alarm, a fan and a display screen; the utility model detects the combustible gas concentration and toxic gas concentration data in the air around the electrical cabinet through the combustible gas detector and the toxic gas detector, and then displays the data through the display screen. When the data detected by the combustible gas detector or the toxic gas detector reaches a threshold, the audible and visual alarm is started through the PLC controller, thereby increasing the safety of the electrical equipment when in use, and controlling the opening and closing of the fan through the PLC controller, thereby reducing the impact of high temperature on the electrical equipment and increasing the protection effect on the electrical equipment.

[0004] However, the above technology has the following disadvantages when used:

[0005] The description in paragraph 0038 of the above document is that "the fan 206 is started by the PLC controller 201, and the working fan 206 performs heat dissipation work in the electrical cabinet 101, thereby reducing the impact of high temperature on the electrical equipment, and then the water vapor carried in the air in the electrical cabinet 101 is adsorbed by the solid desiccant 48, thereby preventing the water vapor from corroding the electrical equipment in the electrical cabinet 101, and then the solid desiccant 48 is dried by the working fan 206". It can be seen that the fan 206 is needed to dissipate heat in the electrical cabinet 101 to reduce the problem of damage caused by excessive temperature of the internal components of the electrical cabinet 101. However, when the fan 206 is not in use, impurities are easy to fall to one side of the second filter 45 through the vent 44. With the accumulation of impurities on one side of the second filter 45, the ventilation efficiency of the vent 44 is easy to be reduced, which increases the problem of damage caused by high temperature of the internal components of the electrical cabinet 101.

[0006] Therefore, a safety protection mechanism for drilling electrical equipment is proposed to solve the above-mentioned drawbacks. Utility Model Content
